Well, got the TM figured out, turns out its table B6605 in the "traction control" section. I reduced the entire table by about 25% and it made a big difference in the shifts. Its only dropping off about 5* during shifts now instead of 10*. Whats odd is its the E80 fuel% chart, whats up with that? Maybe its labeled wrong, not sure. Anyway, thats the table to pull the torque management out of the Allison. Oh, and it feels way better through the shifts now.... Still got a little KR in it, but it was holding about 16* of timing at WOT through the 1/4 run rather well. Intercooler made a huge difference, guess it would when you reduce total IAts by over 120*. I ended up pasting in a stock 8.1L spark table into my tune, then adjusting about -4% of the table from .96kPa - 1.20kPa. Seemed te respond well to that.

 

sounds good, seems like your getting a handle on the tuning

 

I have good teachers..

 

Jimmie, are you able to change the shift points now?

Yes, the allison is pretty much wide open now. The only thing i can think of that i cant do (that i want to do) is manage the grade breaking feature. TCC lock-up, RPM shifts, MPH shifts, TAP cells, tow/haul mode, are all accessible and tunable now.
